Formation of longitudinal and volumetric waves in a vicinity of a cavity of the explosive chamber is investigated. By the received results the conclusion is made, that for an estimation of parameters of waves of pressure on walls of an explosive cavity the shock adiabatic curve of an elastic harbinger, because of affinity of adiabatic curves of an elastic harbinger and a wave of volumetric compression can be used.
